Sorry folks, I have (2) 512's in each system. I first bought the MB, then got he MBP for a job that fell through. I love them both. The MB has the batteyr life and portablilty, the MBP hs the backlit keyboard bigger screen, better speakers, etc. I got the ram for my B-Day. My initial thought was use it the MB being the low end machine, but maxing out the pro sounds sweet also.
Maybe I shouldn't care about the macthed pair of ram and do 1.5gb in each.🙂
